Configuring a DS1 Interface

You can configure DS1 interfaces on CT3, CT1, and CE1 line modules.

CT3 modules are made up of three DS3 line interfaces. Each DS3 line interface multiplexes 28 asynchronous T1 (DS1) channels.
CT1 modules have 24 T1 channels
CE1 modules have 20 E1 channels

To configure a DS1 interface:

In the Instance Explorer, navigate to the DS1 level.
Select the DS1 interface that you want to configure, right-click, and select Configure.

The DS1 Config tab appears in the work area.

Set the DS1 configuration parameters (Table 55).




 Table 55:  DS1 Configuration Parameters 

 Field
 Description

 Name

 Identifier for the interface; generated automatically


 Alias

 Description of the interface; 0-15 characters; default: blank


 IfIndex

 Identifier for the interface on a particular line interface; generated automatically


 Operational

 Current operational status of the interface


 Administrative

 Desired status of the interface: Up/Down; default: Up


 Framing Type


   ESF—T1 framing for extended superframes (ESF) (default)
   SF—T1 framing for superframes (SF)
   CRC4—Cyclic redundancy check (CE1 only)
   no CRC4—(CE1 only)



 Transmit Clock


   Received Timing—Sets the clock source on the active line
   Module Timing—Receives its clocking from a network source
   Chassis Timing—Receives its clocking from the configured system clock



 Operation Mode

 Specifies the type of controller (DS1):

   T1—T1 and CT3 modules only
   E1—E1 module only (Europe)
   J1—T1 module only; J1 variant of the T1 framing (Japan)



 Line Coding


   AMI—Specifies alternate mark inversion; default
   B8ZS—Specifies bipolar with eight-zero substitution; T1 and CT3 modules only
   HDB3—Specifies high-density bipolar 3 line-code type; E1 module only (Europe) 



 Loopback Mode


   None—No loopback specified; default
   Network Payload—Loops the data toward the network
   Network Line—Sets a local loopback at the payload controllers
   Local—Loops back outgoing data from the transmit to the receive side



 DS0 Bundle Time Slots


   Time slots 1-24 (CT3 and CT1) or 1-31 (CE1) 
   An X indicates preallocated DS0 bundle timeslots on the T1 line interface selected



 Allocated Bandwidth (kbps)


   Displays the total amount of allocated bandwidth

Click Save.
